| 摘 要： | 研究了剑叶金鸡菊及其伴生植物鬼针草、羊蹄幼苗的生物量分配、生长和生理特性在不同强度的光生境中(全光照和31％光照)的响应特征,探讨了这些特征与其入侵性的关系.结果表明:(1)光强是影响剑叶金鸡菊入侵的重要环境因子,高光环境下其幼苗较高的相对生长速率( RGR)和植物单位重量的光合效率(Am)与其入侵性密切相关.遮荫下,...

| Abstract: | To better understand its invasion mechanism and comprehensive control,we compared the morphological and physiological traits of C.lanceolata with those of its co-occurring species Bidens bipinnata and Rumex japonicus under two different irradiance treatments(full irradiance and 31% of the full irradiance),then analyzed the correlation between those traits and invasiveness. It was found that C.lanceolata was a light-favoring species,and that the high relative growth rate(RGR)and photosynthetic capacity based... |
